Serotypes and colonization factors of enterotoxigenic Escherichia coli isolated in various countries.
One hundred and six enterotoxigenic E. coli (ETEC) isolated from many geographical areas were serotyped and investigated for the presence of colonization factor antigens CFA/I and CFA/II, the expression of mannose-resistant haemagglutination (MRHA) and the levels of surface hydrophobicity.
CFA/I was found in 6 (17%) of 16 LT+STa+ strains and in 15 (54%) of 28 STa+ strains; CFA/II was found in 16 (44%) of 16 LT+STa+ strains.
None of 42 LT+strains showed CFA/I or CFA/II.
CFA/I was found in ETEC of serotypes O61:
O128:K67 and O153:K-:H45, whereas CFA/II was found in serotypes O6:H-,
O6:K15:H16 and 06:K?:H40.
